摘要
应用灰色系统理论分析采场顶板运动及支架围岩关系两个复杂系统,介绍来压步距与支护载荷两个综合灰色量的灰色预测预报方法,即模型建立、计算过程和应用实例。研究表明,灰色模型能很好地模拟或反映顶板压力参数的变化过程与内在规律。
Grey system is used in this paper to study the overlaying bed movement and the relationship between supports and surrounding rock. The forecasting methods of comprehensive grey parameters (weighting spans and support load) are introduced in the paper, which includes three steps-grey modelssetting, calculating process and practical examples. Studies shod that the grey models can simulate or reflect roof pressure parameters changing and its inner rules.
